If this is an Note: UB [16] is not the same as interframe, and this block has UI16; there is no byte swapping. not changed since the last update of this image area, DataSize is 0 and the Data field is absent.

Analog video contains a large amount of high frequency noise that either needs to be captured at full channel bandwidth, or low pass filtered prior to A / D. Post A / D noise will greatly affect motion detection for interframe (GOP) compression quality.

A-MPDU, the aggregation of multiple MAC-level service data units; Block Ack, which increases efficiency by transmitting multiple data frames followed by only one acknowledgement frame in a transmission block; Greenfield mode, the increased efficiency gained by dropping 802. 11a / b / g backward compatibility; and RIFS, reduced interframe spacing, which minimizes unused radio dead time by cutting the interval time between sent packets.
